While the bags work well enough, I am looking for suggestions as to how to store coffee beans when they are roasted but not yet time to grind.
Freezing does not necessarily entail repeated warming and chilling. One can portion beans when freezing them. Condensation can be mitigated as well by evacuating as much air as possible and allowing the beans to warm to ambient before exposing them to air. There is definitely appreciable benefit to freezing coffee if properly done as beans are perishable and freezing can extend the lifespan of the beans.A lot of folks recommend keeping coffee in the freezer. DO NOT DO THIS. There is no appreciable benefit to keeping coffee beans at low temperature, and the condensation that develops from repeated warming and chilling can leach flavor from the beans.

I store my home-roasts in mason jars in a dark cupboard. This way, I figure if you keep it in multiple smaller jars, when you open the one to use some beans, only air gets at that amount, not the rest that are in their own sealed jars. Obviously, for my home roast, I leave the lid loose for the first 10-12 hours to let them outgas, but after that, I haven't had any issues with jars exploding.

Large mason jar. Large mason jar with a tiny nail hole in the lid for ~24 hours after roasting.

Atlas mason jars that started life holding spaghetti sauce. After a good wash that included a mild vinegar solution. These can hold roughly 13 oz of green beans after roasting.
Purchasing what I can use in a week works best for me. I just make sure I tightly resealing the bag the coffee is packaged with after grinding what I need. I only grind what I need for a double shot each morning.
Having a great local roaster in town helps, and visits to the shop are part of my weekly routine. I only buy their freshest roasts, and the frequent visits allows me to try a great variety of coffee's. On occasion I've gone two weeks between visits - and very rarely see a degradation in the quality of my espresso's (less crema).
